To (LU whmn it may concern:

Be it known that we, HENRY J. PARK and FERDINAND H. Rrns, citizens of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Pump, of which the following is a specification.

The invention relates to improvements in pumps.

The object of the present invention is to improve the construction of that class of pumps employing one or more rotary propellers for lifting the water and to provide a simple and comparatively inexpensive one designed for operation in either bored or dug wells and capable of lifting water the desired height at the expenditure of a minimum amount of power.

A further object of the invention is to provide a compound pump of this character adapted to be constructed of any desired number of sections and capable of operating in wells of different kinds, whether the same be provided with cisterns or pits at the bottom or not.

Another object of the invention is to reduce the friction to a minimum and to provide means for excluding water and sand from the bearings of the rotary shaft.

WVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a vertical sectional view of a pump constructed in accordance with this invention, the propeller and the bearings for the rotary shaft being in elevation. Fig. 2 is a similar view, the propeller and the bearings being in section. Fig. 3 is a detail perspective view of the combined guide and bearing. Fig. 4: is a similar view of the propeller. Fig. 5 is a plan View of the propeller.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a vertically-disposed rotary shaft arranged in suitable bearings of a pumpcasing, which may be of any desired length and which is composed of a plurality of similar sections, the upper section being illustrated in the accompanying drawings. The upper section of the pump-casing comprises a cylinder 2, which is connected by a pipe 3 with a T-shaped coupling or member 1, having a lateral discharge-opening 5 and adapted to be connected with any suitable means for carrying off the water discharged by the pump. The cylinder 2, which may be made of any desired size, is provided with upper and lower rims or heads 6 and 7, the upper rim or head being provided with an exterior recess to receive the upper end of the cylinder and extending into the same, as shown. The flange or portion 8 which extends into the upper end of the cylinder is secured to the latter by rivets 9 or other suitable fastening devices, and the upper end of the rim or head, which is reduced, is provided with interior threads 10 for engaging exterior threads of the lower end of the pipe-section 3. The lower rim or head 7 extends into the lower end of the cylinder 2, and the parts are provided with lefthand screw-threads 11 to prevent the motion of the shaft from unscrewing the parts. The lower portion 12 of the lower rim or head of the cylinder is interiorly threaded to receive the connecting pipe or section 13, which is designed to extend to the upper rimor head of the second cylinder. (Not shown.) Any number of cylinders or. sections may be employed, the sections consisting of the cylinder and the connecting pipes or tubes. The upper end of the casing receives a circular support 14, consisting of a lower exteriorlythreaded tubular portion 15 and an upwardlyextending tubular portion or flange 16. The flange being circular or annular forms a recess or socket for the reception of upper and lower bearing-plates 17 and 18. The bearing-plates 17 and 18 are provided with central openings for the passage of the rotary shaft, and they have annular grooves in their opposed faces to form races for antifrictionballs 19. The antifriction-balls 19 are interposed between the upper and lower bearingplates 17 and 18, as clearly shown in Fig. 2 of the drawings. The upper bearingplate extends slightly above the annular flange or wall 16 of the support 14 and receives a cap 20, which fits over the flange or wall 16 and which is secured to the shaft 1 by means of a clamping-screw 21 or other suitable means. The clamping-screw 21 is mounted in a threaded perforation of a tubular extension or sleeve of the cap. By this construction the weight of the rotary shaft is supported by the top bearing, which enables the shaft to rotate with a minimum amount of friction. A pulley 22 is secured by clamping-screws 23 or other suitable means to the upper end of the rotary shaft and is adapted to receive a belt whereby the pump is operated; but any other suitable means may be employed for operating the pump.

Sand and water are excluded from the top bearing by means of a stufling-box 24, provided with a packing 25, of wool or other suitable material, and having interior screwthreads for engaging a threaded depending tubular extension 26 of the support. The stufling-box is polygonal or in the form of a nut, as clearly shown in Fig. 1, to enable it to be readily engaged by a wrench or other tool.

The vertical shaft is composed of sections the adjacent ends 27 and 28 of which are threaded and are screwed into interiorlythreaded sockets 29 and 30 of a hub 01" body portion 31 of a propeller. The body portion of the propeller is securely clamped on the threaded ends of the shaft-sections by jam-nuts 32 and 33, arranged on the threaded portions of the shaft-sections and engaging the ends of the hub or body portion 31. The propeller, which operates within the lower portion of the cylinder, is provided with three spirally-arranged blades 34. These blades, which are set at an inclination, are substantially sector-shaped and their terminals are spaced apart to provide passages for water. The adjacent ends of the blades are slightly overlapped, as clearly shown in Fig. 5.

Within the upper portion of the cylinder is arranged a combined guide and bearing consisting of a spider provided with a central tubular portion 35 and having radial wings or arms 36, which extend to the walls of the cylinder and which are provided with laterallyextending curved flanges 37 The curved flanges 37, which fit against the walls of the cylinder, are secured to the same by bolts 38 or other suitable fastening devices. The tubular portion, through which passes the shaft, is provided at its lower end with an inwardlyextending annular flange 39, forming a seat for a packing 40, of wool or other suitable material, which effectually excludes water and sand from the lower portion of the hearing. The tubular portion 35 forms a casing for a bushing 41, of brass or other suitable material, which terminates short of the upper end of the tubular portion 35 to provide a space for an upper packing 42, of wool or other suitable material, which excludes water and sand eon rm from the upper end of the bearing. The upper end of the bearing portion 35 is exteriorly threaded to receive an interiorly-threaded cap or nut 43, which is adapted to compress both of the paekings, whereby the same are forced tightly against the shaft. If desired, a metal gland may be arranged within the cap or nut for-directly engaging the upper packing to compress the same within the tubular portion of the combined guide and hearing. The arms or wings of the combined guide and bearing extend from the lower end of the tubular portion to within a short distance of the frame thereof, and there is sufficient area to check the rotation of the water lifted by the propeller, thereby rendering the operation of the latter more effective.

Oil is supplied to the top bearing by means of an exterior oil-cup 44, mounted on a tube 45, which pierces the vertical flange or wall 14 and communicates with the socket or space inclosed by the same. The bearings for the rotary shaft reduce the friction to a minimum and enable the pump to be operated with a minimum amount of power. When the shaft is rotated, the propellers elevate the water, and it will be apparent that by increasing the number of the sections and the propellers the water may be lifted to any height. The pump is adapted to operate in any kind of well, and sand and water are effectually excluded from the bearings.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a device of the class described, the combination of a casing, a shaft, a propeller mounted on the shaft, a combined guide and bearing mounted within the casing and provided with a central tubular portion receiving the shaft, a bushing located within the tubular portion and arranged on the shaft, and upper and lower packings.
